What Makes a Robot Vacuum Cleaner Best?

The top robot vacuums have a powerful engine and a robust set of bristles or rollers. They also have large dustbins and large battery life.

Certain models use smart mapping to map homes, and they can be able to pause, recharge and clean up right where they started. They can also set no-go zones and identify different surfaces.

Object Avoidance

Object detection is a key feature for robot vacuums as it helps them to avoid running into small objects such as cords, toys, socks or shoes that are not on the floor, but on furniture. The systems utilize cameras built into the system to identify objects that appear in an AI database, and then teach the vacuum how to avoid them. The Eufy S1 Pro, for example, utilizes a mix of sensors that include 3D Time of Flight (sending light pulses to determine the distance and depth of the surrounding objects) and 3D Structured Light (beaming a pattern of lights onto the space and analyzing the distortion of light to create a map) to efficiently steer away from obstacles.

A recent addition to the arsenal of obstacle avoidance is artificial intelligence and visual interpretation, which allows robots to recognize and understand what they're observing. This software utilizes two cameras to view the world and analyze it in real time. The ECOVACS DEEBOT uses this software to detect up to 30 types of objects such as cables, shoes and pet poop.

Some models also use LiDAR to navigate. The technology emits laser beams and measures the time it takes them to bounce back at surrounding surfaces to create a live 3D map of the surrounding. This can be used to detect walls, furniture, and even stairs. However, it might not work as well in dim lighting or when working with reflective or transparent objects.

Regardless of which sensor or cameras are utilized regardless of the camera or sensor, a long battery life is important to ensure that your robot will be able to completely fill your home without the need to return to its dock to recharge. Choose a model with an endurance of at least 80 minutes or longer depending on the dimensions and layout of your home.

Self-Emptying Bases

Certain robot vacuum cleaners have self-emptying bases that can reduce the frequency with which you need to empty your bin. They're considered to be a luxury feature and typically add to the cost of a robot.

The most effective robots have bases that are able to hold either bins, or a movable dustbin. You can open it and empty it when full. This will save you time by reducing the amount of time you are occupied with deciding when to empty the dustbin.

All the robots we reviewed have self-emptying bases. The only exception is the Roomba I3+. It's a pity, since the robot is extremely efficient. It had the best mapping results of all the robots that we tested and has excellent navigational capabilities. It has a good mowing ability and a docking system that will empty the water tank on its own when it is needed.

It doesn't have iRobot's advanced obstacle avoidance technology and digital keep-out zone, however it can get tangled up in rugs and cables, and is unable to see rogue shoelaces or socks. It's a great option for a small home that's well-maintained.

Other strong points include its navigation technology, which includes bump sensors as well as a drop sensor, and its ability create a map of your entire home by using lasers and cameras. It is simple to use, has a range of settings and modes and is a great choice for mowing or vacuuming. Its smart-home functionality allows it to be controlled with voice commands made using Amazon Alexa or Google Assistant. This makes it easier to use if have multiple smartphones or tablets and do not want to carry an additional remote vacuum.

App Controls

Certain robots come with Wi-Fi connectivity, allowing you to control them using your tablet or smartphone. This convenience is especially helpful in large homes with multiple floors, where you may have to navigate your way down a staircase before the robot is able to get to the bottom. This removes the need for an extra long cord to move your furniture without worrying about the robot getting caught in it or running out of power when cleaning.

The app serves as a single-stop control center to monitor and schedule tasks. The app allows you to customize the cleaning mode, power and water level of your robot cleaner. This feature is particularly useful for homes with different types of flooring, like tile and carpet. You can assign the robot the proper power and cleaning mode to clean each area.

Some models come with a built-in video camera that transmits live video directly to the application. These models are a great choice for pet owners and parents of children who wish to keep an eye on the robot while it's in operation. Other smart robots come with sensors that can detect when they've reached the edges of a room and then return to their base to dock. This prevents them from overrunning the area and also ensures that they've cleaned the surfaces within your home.

Some models can automatically empty the dustbin and even wash their mop heads and blow dry between cleaning sessions. This eliminates the need for manual maintenance, and the robot cleaner will work better over a longer period of time. You can also select a model with a longer battery life, which will help you avoid the hassles of mid-cleaning recharging.

Sensors

A lot of robot vacuums are fitted with sensors that allow them to navigate around your home. They can be used on area rugs, carpets, and hard floors such as tiles and wood. They're not an alternative to a full-size canister or upright cleaner, but provide superior suction and a fantastic way to keep your floors clean in between deep cleanings.

Sensors assist the automatic hoover robot in navigating your space by detecting obstacles and avoiding falling down steps. You can also create virtual and physical "no go" zones using boundary strips or a virtual wall (like those used by Eufy), to prevent the robot entering specific areas of your home. Certain robots have cliff sensors that warn you when your robot is about to crash into the edge of a cliff.

The type of navigational system that robot employs is determined by your budget and layout of your home. Some of the most advanced robotic vacuums employ LiDAR sensors to scan and map areas to ensure precise navigation. These systems are costly however they give the most efficient results. The budget models that have basic navigation bumps are less precise and can miss some places. These models are good at avoiding major obstacles but can fail to spot dirt in crevices and around baseboards.

Look for a model with an extra-large dust bin as well as an extended battery life. There are also models that can recharge and resume where they left off after they dock, which can save you time. In addition to navigation it is possible to get the most out of your robot vacuum by prepping for each cleaning session. Check that power cords, toys and other debris are removed and out of the path of the robot, and empty the bin every cleaning. Clean the sensors and charging port to keep your robot healthy.

Navigation

The best robot vacuum deals robot vacuums can create a digital map of your home's interior using mapping technology in the first cleaning session. It allows them to recognize different the different textures, like hard and carpeted floors, and ensures that all areas are thoroughly cleaned. Mapping also saves your robot from having to clean the same spots, which improves efficiency and reduces battery usage. A lot of high-end models offer the option to save a map of your house to use in the future which is a great feature for larger homes.

Most robotic vacuums feature some kind of obstacle avoidance, which prevents them from running into cords, shoes, or socks. These sensors are not always able to detect smaller items. Manufacturers added sensors to robots around a year ago. They were able to detect and avoid household objects that sensors could not. These include wall and cliff sensors, which work by bouncing infrared light beams off surfaces to calculate distances.

Certain sensors are built directly into the robot base, while others need to be purchased separately. These sensors assist the robot to move safely and avoid falling down stairs, and stay clear from clutter. Some models have anti-drop sensors that automatically stop the robot from colliding with furniture and walls.

LiDAR mapping the most advanced navigation system is a feature that you should consider when buying robot vacuum. This type of system uses a spinning laser sensor mounted on the top of the robot to map your home. It can map your home by bouncing infrared beams off your walls and furniture. This helps it plan efficient paths and clean your entire home.
